抗氧剂能有效降低塑料材料自氧化反应速度、延缓塑料材料老化降解的塑料助剂,其应用几乎涉及所有的聚合物制品。塑料用抗氧剂通常包括酚类抗氧剂、磷类和硫类辅助抗氧剂以及金属离子钝化剂等。 Antioxidants can effectively reduce the self-oxidation of plastic materials, slow down the degradation of plastic materials plastic additives, the application of almost all of the polymer products. Plastic antioxidants usually include phenolic antioxidants, phosphorus and sulfur-based auxiliary antioxidants and metal ion passivation agent.
